一、電池片回收有什么作用

1、減少對環境的污染壓力

如今，隨著社會經濟的發展，社會環境正面臨嚴峻的考驗。一方面，不可生資源的數量正在減少。另一方面，一些污染現象還在不斷破壞環境的平衡結構。比如說部分人隨意丟棄廢舊的電池片。這種情(qing)況下(xia)，會對(dui)環境(jing)的土壤、水源(yuan)等產生嚴重危害。

2、提高資源的使用效率

廢舊電(dian)池(chi)片并(bing)不(bu)(bu)是沒有用(yong)途，其(qi)實，廢舊電(dian)池(chi)片可以被再次(ci)利(li)用(yong)，從而可以提高資(zi)源(yuan)的(de)(de)(de)(de)使(shi)用(yong)效率，尤其(qi)是一些不(bu)(bu)可再利(li)用(yong)的(de)(de)(de)(de)資(zi)源(yuan)能(neng)夠得到較好的(de)(de)(de)(de)保(bao)護(hu)，既能(neng)夠延長資(zi)源(yuan)的(de)(de)(de)(de)使(shi)用(yong)時(shi)限，還能(neng)降低部分(fen)物(wu)資(zi)對環(huan)境(jing)造成的(de)(de)(de)(de)污染(ran)。

3、節省了一定的生產成本

從(cong)電(dian)池(chi)片回(hui)收公司了(le)解到，他們使用廢舊電(dian)池(chi)為原料，生產新的(de)電(dian)池(chi)成本得(de)到了(le)大幅度降低，實現了(le)“雙贏”的(de)局(ju)面。

在日常的(de)工作(zuo)生活(huo)中，建議(yi)大(da)家要(yao)妥善(shan)處理好廢舊(jiu)(jiu)電池片(pian)(pian)，尤(you)其(qi)是不能隨意處置，比(bi)如說(shuo)丟棄在垃圾堆(dui)里，那樣將會(hui)造成很大(da)的(de)危(wei)害，盡可能將廢舊(jiu)(jiu)電池片(pian)(pian)收集起來送到(dao)(dao)電池片(pian)(pian)回(hui)收公司(si)，在實現廢舊(jiu)(jiu)電池片(pian)(pian)回(hui)收的(de)同時，對保護環(huan)境起到(dao)(dao)了很好的(de)作(zuo)用。

三、太陽能電池片怎么進行回收

電池(chi)片可(ke)以回收(shou)(shou)，可(ke)以從(cong)太陽(yang)能電池(chi)中回收(shou)(shou)純硅。

太陽能電池主要含有硅（約91.6%重量）。它還包含其他材料，例如底層的鋁，頂層的銀電極，以及頂層的鉛和抗反射涂層。p型和n型硅晶片位于抗反射涂層和鋁層之間。太陽能電池片藍色層(ceng)是(shi)抗反射(she)涂(tu)層(ceng)（SiNx），白(bai)線是(shi)銀(yin)電極。太陽(yang)能電池片的底部為(wei)鋁層(ceng)。為(wei)了去除這(zhe)些材料(liao)（鋁、銀(yin)、鉛和抗反射(she)涂(tu)層(ceng)），需使用(yong)化學處理方法。

首先，氫氟(fu)酸或氫氟(fu)酸與其他化(hua)學品的(de)(de)混(hun)合(he)物用(yong)于去除(chu)太(tai)陽(yang)能(neng)電池(chi)的(de)(de)抗反射涂層、銀、鉛(qian)和(he)pn結。由(you)于氫氟(fu)酸是劇毒(du)和(he)腐蝕性化(hua)學品，因(yin)此在目前的(de)(de)工作中不再(zai)使(shi)用(yong)氫氟(fu)酸。每一(yi)層都使(shi)用(yong)化(hua)學處理一(yi)層一(yi)層地去除(chu)。

用(yong)濃NaOH溶液(ye)(ye)處理(li)(li)后(hou)去(qu)除鋁層。在反應過(guo)(guo)程(cheng)中(zhong)(zhong)(zhong)形成的(de)氫氣被收(shou)集在一(yi)個(ge)腔(qiang)室中(zhong)(zhong)(zhong)并(bing)(bing)可用(yong)作燃料。通過(guo)(guo)過(guo)(guo)濾從NaOH溶液(ye)(ye)中(zhong)(zhong)(zhong)分(fen)離(li)(li)氫氧(yang)化(hua)鋁。類似地，通過(guo)(guo)用(yong)HNO3處理(li)(li)去(qu)除銀(yin)和鉛(qian)(qian)(qian)(qian)。收(shou)集釋放的(de)NO2并(bing)(bing)可用(yong)于生產(chan)硝(xiao)酸。分(fen)離(li)(li)硝(xiao)酸銀(yin)，溶液(ye)(ye)用(yong)HCl處理(li)(li)，形成氯化(hua)銀(yin)。濾出沉淀的(de)氯化(hua)銀(yin)。此外，將溶液(ye)(ye)用(yong)NaOH處理(li)(li)以從溶液(ye)(ye)中(zhong)(zhong)(zhong)分(fen)離(li)(li)鉛(qian)(qian)(qian)(qian)化(hua)合物（PbO）。氧(yang)化(hua)鉛(qian)(qian)(qian)(qian)轉(zhuan)化(hua)為(wei)氫氧(yang)化(hua)鉛(qian)(qian)(qian)(qian)，過(guo)(guo)濾沉淀的(de)氫氧(yang)化(hua)鉛(qian)(qian)(qian)(qian)。
